If iPhone is locked and somebody calls on Skype, push notification appears.
I think it’s simple push notification as other app servers send.
But when the call ends (and we didn’t respond, so the call is missed) push notification disappears from lockscreen! It is not stored in notification center nor recent notifications list on lockscreen.
So how to do this?
How to implement calling of push notifications?
Does Skype have special priveleges or is it also available for regular developer to implement?
No they don’t.
Skypeuses voip andAppleallow apps that use location, voip and audio to run in background, soSkypeis set in theAppName-Info.plistfileRequired background modestovoipand what you see is not a push notification, but a local notification controlled by the running app.
